We investigated the physiological basis for development of obesity in uncoupling protein-diphtheria toxin A chain (UCP-DTA) transgenic mice. In these mice the promoter of the brown adipose tissue (BAT)-specific UCP was used to drive expression of DTA, resulting in decreased BAT function and development of obesity and insulin resistance (Lowell, B. B., S. V. Susulic, A. Hamann, J. A. Lawitts, J....
Abstract Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production without using SMG is not economically feasible. However, SMGs are non-essential once an intact transgenic plant has been established. Eli...
Background: Canola is an agro-economically oilseed crop. Yield loss due to fungal disease of stem rot caused by Sclerotinia sclerotiorum is a serious problem in canola cultivation. Thaumatin-like proteins are large groups of the pathogenesis-related proteins which provide resistance to the fungal infection in response to invading pathogens and play a key role in plant defense s...
low phosphorous (p) availability in soils limits production of soybean [glycine max (l.) merr.] around the world. this study was conducted to determine whether exogenous expression of the rice (oryza sativa l.) phosphates transporter gene ospt2 would increase inorganic phosphates (pi) acquisition and improve yield in transgenic soybean. cotyledonary-node explants of the soybean were inoculated ...
through an application of genetic engineering, genes from a soil bacterium bacillus thuringiensis (bt) which confer resistance to pests were transferred into rice. successful employment of genetic engineering in traditional breeding programs is dependent upon stable transmission of transgene in transgenic varieties. three different segregating f2 populations were developed from a cross between ...
Liver fructose-1,6-bisphosphatase (FBPase) is a regulatory enzyme in gluconeogenesis that is elevated by obesity and dietary fat intake. Whether FBPase functions only to regulate glucose or has other metabolic consequences is not clear; therefore, the aim of this study was to determine the importance of liver FBPase in body weight regulation. To this end we performed comprehensive physiologic a...
cotton cultivar coker has been already transformed with recombinant pbi121-chi via agrobacterium tumefaciens. the t-dna region of pbi121-chi carries the chitinase (chi ) gene from bean and is under the control of the camv35s promoter. t1 and t2 progenies of transgenic cotton containing the chi gene were used in this study. polymerase chain reaction (pcr), southern and western blotting data con...
The transgenic papaya is a valuable strategy for creating plants resistant to papaya ringspot virus (PRSV) infection and increasing production. This study was further performed to evaluate the comparative toxicity effects of the newly developed transgenic line of the fruits of two backcross transgenic papaya lines (2210 and 823) and one hybrid line (823-2210) and compare to their parent non-tra...
an endochitinase gene (chit36) was isolated from the biocontrol fungus trichoderma atroviride. chit36 was overexpressed under the camv35s constitutive promoter in canola. transformation of cotyledonary petioles was achieved via agrobacterium tumefaciens. the insertion of transgene was verified by pcr and dna dot blotting. rt-pcr analysis indicated that the transgenic canola was able to express ...
background: a highly efficient genetic transformation system is essential for a successful genetic manipulation of the african violet (saintpaulia ionantha wendl.).objectives: developing a particle bombardment-based genetic transformation system for the african violet.materials and methods: a local cultivar of the african violet from guilan province was used for transformation experiments. the ...
